One of my R510 APs won't upgrade and remains invisible to the Vsz
Hi folks. I recently purchased 25 APs R510. After doing some config (APgroups, WLAN, WLAN groups) on the controller i started to connect them to LAN. One of them won't upgrade and remains invisible to the Vsz. It's got the FW 126.96.36.199.354 and the Vsz has 188.8.131.52.675. The AP gets IP from DHCP and is visible in the Vsz CLI by the command "show ap [MACaddress]" there you can see IP adress and FW version. I've factory reset it and upgraded the FW to stand alone FW 184.108.40.206.1347 and then reconnect but no success. What happened was it degraded itself to the old FW version. I've also tried to SSH into it and the command "set scg ip " No luck whatsoever. Is there anything else I could try?
